The 31 facts
Reading and spelling
Day 1: Dyslexia can affect reading accuracy, reading speed, and spelling.
Reading accuracy is only one part of the picture. The International Dyslexia Association’s 2025 definition describes dyslexia as difficulty with word reading and/or spelling involving accuracy, speed, or both. A child’s full learning profile matters.

Day 2: Letter reversals alone do not identify dyslexia.
Some young children reverse letters as they learn to read and write. Some children with dyslexia reverse letters; many do not. Look at the broader pattern of reading and spelling skills.

Day 3: Strong spoken answers can hide difficulty with written words.
A child may explain an idea clearly aloud and still find reading or writing it difficult. Comparing spoken responses with independent reading and written work can help adults notice where support is needed.

Reading and spelling
Day 4: Spelling can reveal gaps that familiar reading may hide.
A child may recognize familiar words in a practiced passage but struggle to spell or decode unfamiliar words. Reading and spelling offer different clues about literacy skills.

Day 5: Accurate reading and fluent reading are related, but different.
Accuracy is reading the words correctly. Fluency also includes reading at an appropriate pace. Both matter for understanding connected text.

Day 6: Dyslexia is not a measure of intelligence.
Dyslexia occurs across the range of intellectual ability. Reading difficulty does not tell you how capable a child is.

Reading and spelling
Day 7: Guessing from context can hide whether a child can read the word.
Pictures and sentence meaning help readers understand, but they do not show whether a child can decode the printed word. Encourage attention to the letters and their order.

Day 8: Audiobooks provide access. Reading instruction builds reading skills.
Listening to books can give students access to stories and information while they receive direct instruction in reading. Audio should support access, not replace instruction in word reading.

Reading and spelling
Day 9: Dyslexia can affect spelling as well as reading.
Reading and spelling both involve connecting sounds and written patterns. A child who reads better than they spell may still need support with written words.

Day 10: Dyslexia is lifelong. Reading and spelling skills can improve.
Dyslexia does not simply disappear with age. Targeted instruction and appropriate supports can help people build skills and manage challenges over time.
Source: Understood
Day 11: Dyslexia does not look the same in every child.
Children can have different strengths and challenges across decoding, spelling, fluency, and other parts of literacy. One child’s experience is not a checklist for every child.
Source: Understood
Day 12: Dyslexia is language-based, not a vision problem.
Dyslexia involves language processing and word reading. It is not caused by seeing letters differently or by a basic vision problem.
Source: Understood
Instruction and support
Day 13: Connecting speech sounds to letters supports reading and spelling.
Written words represent the sounds and meaningful parts of language. Explicitly teaching those connections can support both decoding and spelling.

Day 14: A child may understand more by listening than by reading independently.
Listening comprehension and independent word reading are not the same skill. Read-alouds and audiobooks can keep students connected to rich ideas while they work on reading.
Source: IDA Structured Literacy
Day 15: Reading comprehension depends partly on word reading and language understanding.
Understanding a text draws on recognizing its words and understanding the language. If word reading takes most of a student’s effort, comprehension can be affected.

Day 16: Dyslexia may affect writing as well as reading and spelling.
Written expression can be difficult when spelling and word-level skills take considerable effort. A child’s writing may not show everything they know.

Reading and spelling
Day 17: Recognizing a familiar word is not the same as decoding a new one.
Memorized or familiar words can be recognized quickly. Decoding helps a reader work through words they have not seen before. Both experiences matter when looking at reading progress.

Day 18: Pictures can support meaning, but they cannot teach the printed word.
Context is useful for understanding a story. To learn to read a word, students also need to attend to its letters, sounds, and spelling pattern.

Instruction and support
Day 19: Structured Literacy teaches how written language works.
Structured Literacy explicitly teaches language skills, including sounds, spelling patterns, syllables, meaningful word parts, sentences, and text.

Day 20: Systematic instruction builds new learning on what came before.
In systematic, cumulative instruction, skills are taught in an organized sequence and reviewed as students learn more complex patterns.

Day 21: Reading instruction includes more than phonics.
Strong literacy instruction addresses foundational skills such as decoding and spelling, along with fluency, vocabulary, comprehension, and writing.

Reading and spelling
Day 22: Reading and spelling use many of the same sound-letter connections.
Reading maps written symbols to spoken words. Spelling maps spoken words to written symbols. Teaching both directions helps reveal and build literacy skills.

Day 23: Fluency is more than speed.
Fluent reading involves accuracy and an appropriate pace. The goal is meaningful, comfortable reading—not racing through a passage.

Day 24: Listening can keep grade-level ideas within reach while reading skills grow.
Audiobooks and read-alouds give access to worthwhile texts. They can sit alongside explicit instruction that helps students read words for themselves.

Day 25: Dyslexia is lifelong, but its effects can change over time.
A person’s reading and spelling needs may shift with age, instruction, tools, and the demands they face. Lifelong does not mean unchanged.

Instruction and support
Day 26: Early language signs can show up before children learn to read.
Rhyming, syllables, and noticing the sounds in spoken words are early language skills related to later literacy. A concern is a reason to pay attention and seek guidance—not a diagnosis on its own.
Source: IDA Structured Literacy
Day 27: A screening can flag risk. It cannot diagnose dyslexia by itself.
Screening helps identify students who may need closer follow-up. A full evaluation considers the child’s broader learning profile and other possible explanations.
Source: Understood
Day 28: A struggling reader can receive help before a diagnosis is settled.
Support can respond to the skills a student needs to learn. Families can ask what reading data show, what instruction is being provided, and how progress is being checked.
Source: IDA 2025 Definition
Day 29: Practice works best when it targets the skill being taught.
Repeating reading tasks without knowing the student’s skill need can miss the mark. Effective instruction is planned, explicit, and responsive to student performance.

Reading and spelling
Day 30: The letters in a word matter. Guessing can hide decoding difficulty.
The spelling and order of letters distinguish written words. A student needs to learn to use those print patterns—not rely on a picture or sentence to guess.

Understanding dyslexia
Day 31: Reading difficulty does not measure a child’s effort or potential.
Dyslexia is not caused by laziness or lack of desire to learn. When reading is hard, the useful question is what skill needs to be taught and what support will help.

What to do next
If your child is having a hard time with reading or spelling, pay attention to more than whether they can read a familiar passage. Reading accuracy, pace, spelling, and how much effort the task takes can all matter. You can explore the Dyslexia guide or find a next step for your family.
